Profile: The 28-year-old southpaw is one of the reasons the Pirates bullpen was so fantastic this year. Though his first strike rate remained nearly identical to his previous two seasons, his walk rate plunged and he also benefited greatly from the Pirates defense. Although nowhere near as dominant against right-handed batters as lefties, he's not necessarily a LOOGY, as a 4.23 xFIP suggests that he doesn't need to immediately be pulled when a righty is at the plate. His strikeout rate should rebound given a healthy swinging strike rate, but he's nothing more than a solid middle reliever who will only earn value in leagues that count holds. (Mike Podhorzer)

The Quick Opinion: With no chance at closing out games, Watson's fantasy value is limited to leagues that include holds as a category. He does possess solid skills though and should see a strikeout rate rebound, so he's not a terrible option as your last pitcher in an NL-Only league.

Profile: A top left-handed set up man, Tony Watson enjoyed another stellar year in Pittsburgh and recorded his fourth consecutive year of posting a better ERA and FIP than the season before. Watson was already good and has continued to improve -- he is now one of the best and most reliable relievers in the game. Combining a mid-90's fastball with a solid changeup, Watson has improved so much against right-handed hitters that he is certainly a candidate for saves should something happen to Mark Melancon. Do not count on double-digit wins again, as the 10 he won last year would certainly be a fluke result for any reliever, but he will receive a ton of holds and is about as solid a handcuff as there is around the league. (Ben Duronio)

The Quick Opinion: Watson is one of the top set up men in the game and is almost certainly next in line for saves in Pittsburgh. He can get both lefties and righties out at a high rate, and if something were to happen to Mark Melancon, he could become one of the top closers in all of baseball. Target him if you are looking for a quality handcuff or if you are in a holds league.

Profile: The Pirates like to lean on their relievers, and they've had a couple good ones in recent seasons. Over the last three years, Mark Melancon has thrown the second most relief innings in baseball (218.2 innings). Guess who ranks first? Watson has thrown over 70 frames in each season since 2013 for a total of 224.1 innings. The setup man has performed well over the period with a 1.97 ERA, 3.38 xFIP, 7.90 strikeouts and 1.77 walks per nine. The southpaw generally hums around 94 to 95 mph with his fastball. However, he had a few games with reduced velocity late in the season. It's something to watch since reduced velocity can be a leading indicator of injury. Watson usually holds his opponents to a below average batting average on balls in play and home run per fly ball ratio. That's how he consistently outperforms his FIP and xFIP. By runs allowed based wins above replacement (RA9-WAR), Watson tied as the fifth best reliever of the 2015 season. (Brad Johnson)

The Quick Opinion: Watson produces good peripherals, but he also outperforms them on a regular basis. The result is a frequently used, full inning, left-handed reliever. He's one of the best in the league at run prevention.
